Hello all, I have a couple of questions regarding the Walipini Greenhouse. I'm really serious about building one roughly about 100ft long by 50ft-80ft wide and 8ft-10ft in depth. My questions are as follows. 1. Can it be built in the round top style, or does it have to be in the sloped top angle? 2. What type of material would be best for retaining the side walls? Can rock be used as in a Gabion wall? Or would a concrete wall work best? Any advice is helpful. Thank you for taking the time to read this.
